Electric 3-Way Ball Valve: Versatile Solution for Industrial Fluid Automation

I. Technical Overview

Electric 3-way ball valve is a high-end automated device designed for medium diversion, confluence, and direction switching in industrial pipelines, covering DN15~DN600 (1/2″~24″) with T-type and L-type structures. The T-type enables arbitrary connection of three channels for splitting/mixing, while the L-type achieves 90° direction switching between two channels, suitable for water, gas, oil, and other media. Made of WCB cast steel or CF8M stainless steel, with PN16~PN25 pressure rating and low-to-medium temperature resistance, the electric actuator supports 220VAC, 24VDC, and other power inputs, widely used in petrochemical, HVAC, and water supply systems.

II. Core Product Features

(A) T/L Dual-Mode 3-Way Structure

T-Type Diversion/Confluence: Three-channel design supports “1-inlet 2-outlet” or “2-inlet 1-outlet” for medium distribution/mixing, ideal for chemical reactor material switching and boiler feedwater systems;

L-Type Direction Switching: Vertical connection of two channels for medium redirection (e.g., hot standby pipeline switching), with ±0.5° switching accuracy;

Low Flow Resistance: Flow path complies with ASME B16.34, resistance coefficient ≤0.9, reducing pressure loss by 35% compared to globe valves, saving ~15,000 kWh annual pumping energy.

(B) Efficient Electric Drive System

(C) Material & Structural Advantages

Body Material: WCB cast steel (tensile ≥485MPa) for standard applications, CF8M stainless steel (316L) for acid-alkali resistance in chemical media;
